The EML1 gene encodes a protein that belongs to the family of microtubule-associated proteins (MAPs). Microtubules (MTs) are components of the cytoskeleton with important role in cell motility, cell morphogenesis and cell division among others. MAPs are major accessory proteins on MTs, and function in the regulation of MT assembly, organization and dynamics. The most abundant MAP was identified in dividing sea urchin embryos, and was therefore called the echinoderm MT-associated protein (EMAP). EMAP localizes to the MTs of the first cleavage mitotic spindle as well as with MTs in adult coelomocytes, indicating its involvement in the regulation of MT assembly during the cell cycle. The human EMAP (HuEMAP) is a 79-kDa protein that is similar to EMAP, sharing a unique hydrophobic EML protein domain (HELP; hydrophobic echinoderm–microtubule-associated-like protein) and a variable number of WD-repeat-containing proteins. Each WD repeat folds into a structure of β-strands and β-turns that takes on the appearance of a propeller, with the most accessible and usually variable regions serving as potential sites of protein-protein interactions. The HuEMAP gene is mapped on the 14q32 locus, which is characterized as a tumor suppressor locus in a variety of cancers and as the Usher syndrome type Ia locus. Mutations in this gene associated with HbF response to hydroxyurea in patients with sickle cell disease, while the exact mechanism of action is not currently known.
